after effects to iDVD

hello... I'm trying to author a dvd using iDVD. I've rendered a comp out from after effects using the animation codec with no compression. it's only a couple of minutes long and a 2GB file. when i drop it into iDVD, burn the disc, then play it, the quality looks fairly horrible. could anyone give me a suggestion on how to do this? i've seen suggestions to bring the quicktime into final cut, then go to iDVD from there, but I don't have final cut. thanks in advance!!
